About Me

Beginning in May 2012, the California Public Utilities Commission began testing mobile broadband performance of the four major providers and reporting on the results. The CPUC tests 1,990 locations twice a year. Tests include throughput (TCP), latency, UDP packet loss, and jitter. With these metrics, we are able to estimate network quality for streaming voice (VoIP), streaming video, and interactive video. The results are available on the CPUC interactive broadband map as well as on the CPUC's website. We also offer both iPhone and Android speed test apps for the public to do crowdsourced testing. Search for "CalSPEED" on iTunes and Google Play. The results are uploaded the California Interactive Broadband map every 24 hours.
